The B4041 is a two-terminal, temperature compensated, band-gap voltage reference, which provides a fixed 1.25V output for input currents between 500 A to 5mA. The bandgap voltage (1.225V) is independently laser trimmed from the output voltage to achieve a very low tempco, then the output voltage is laser trimmed to 1.225 volts. This trimming technique and the low tempco (A grade 50 ppm/ C) thin film resistor process gives a very stable device over the full temperature range. The B4041 is available in the sub-miniature (3mm x 1.3mm) SOT-23, SO-8 surface mount package, or TO-92 package. The operating temperature is -40C to 85C.
